Claims. (01. 34-79) This invention relates to a hair drying apparaan improved suction hood or nozzle for use with a dehydrating device of this kind.

To the foregoing objects and to others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be hereinafter referred to and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a detail side elevation partly broken away of a hair drier and dehydrator constructed according to an embodiment of this invention,

Figure 2 is a fragmentary top plan of the device.

Figure 3 is an enlarged vertical section of the suction member with the moisture collector connected thereto,

Figure 4 is a bottom plan of the suction and end flanges I2 and downwardly extending side flanges I3. A suction member generally designated as M is mounted on the base member In and comprises a hollow base l5 formed with lower base flanges 16 which are secured by fastening devices I! to the base plate I I.

A cylinder I8 is mounted on top of the base I5 and is provided with a plurality of heat dissipating vanes or blades 19. A piston 20 is slidable in the cylinder l8 and is connected to a crank shaft 2| by means of a connecting rod 22. The cylinder 18 has detachably secured to the upper end thereof a head 23 which is secured to the cylinder I8 by fastenin devices 24. The head 23 has an intake port 25 formed therein which is normally closed by a spring-pressed Valve 26. An upstanding cylindrical boss 21 is formed integral with the head 23 and extends upwardly from the intake port 25. The boss 21 is formed with a flange 28 on which a cylindrical connector 29 is adapted to be secured. The connector 29 is formed with a lower flange 30 secured by fastening devices 3! to the flange 28. A valve stem guide member 31 is mounted within the upper end portion of the boss 2'! through which the valve stem 32 slidably engages. A spring 33 constantly urges the valve member 26 to a normally closed position. An intake hose or flexible duct 34 is connected with the connector 29 and is of substantial length so that the opposite end of the hose or duct 34 may be positioned adjacent the head of a patient from which the moisture is being withdrawn.

The head 23 is formed with an outlet or exhaust opening 35 having a valve seat 36 on which an exhaust valve 3'! normally engages. An upstanding cylindrical housing 38 is fixed to the upper side of the head 23 and extends upwardly from the exhaust port 35. A valve stem guide member 39 is disposed interiorly of the housing 38 and the stem 40 of the valve 31 slidably engages through the guide 39. A spring 4! constantly urges the valve member 37 to a normally closed position. The housing 38 has a cap 42 detachably mounted on the upper end thereof and the housing 38 is also formed with a laterally extending exhaust nipple 43. A moisture collector or receiver 44 is disposed on one side of the cylinder 18 and includes a threaded cap 45 mounted on the upper end of the receptacle 46. The receptacle 46 may be made of transparent material and the cap 45 made of metal or other suitable material.

The collector 44 is held in outstanding relation with respect to the cylinder 18 by means of.a receptacle supporting ring 41 which is fixed to the cap 45. -The ring 4! includes a pair'of inwardly extending arms 48 having an eye 49 en gageable beneath the head of a fastening member 24. In order to provide a means whereby the transparent receptacle 43 may be held against breakage by contact with the metal forming the suction member 14, a rubber ring 50 is mounted on the receptacle member 46 to'a point adjacent the lower end thereof and the rubber or resilient member 50 is adapted to engage the upper portion of the base 15. The cap 45 is provided with ner hood 6|.

an upwardly extending intake nipple 5| about which a flexible hose 52 is adapted to engage. The opposite end of the hose 52 is adapted to telescope the nipple 43 so that the water and air discharged through the nipple 43 will be discharged into the collector 44. The cap 45 is also provided with a second upstanding nipple 53 disposed in spaced relation to the nipple 5| with which one end of an outlet hose 54 is adapted to engage.

A combined suction and exhaust hood and hair heating member generally designated as 55 is adapted to be connected to the opposite ends of the hose 34 and the hose 54. The hood structure 55 includes an outer shell or housin 56 which is outwardly flared and is substantially oval in transverse section. The outer shell or housing '56 is formed with a'rearwall 51 at the reduced end thereof and a. nipple 58 constituting the suction portion of the hood, is fixed to the wall 51. The hose 34 is adapted to telescope over the nipple 58. The large end of the outer shell 56 is formed with -a.marginal flange 59 about which a rubber casing 60 is adapted to engage. An inner hood 6| is mounted within the outer shell or casing 56 and is substantially smaller in size than the outer shell 56 so as to thereby form an air space 62 therebetween. The inner hood 6| is formed with a rear wall 63 at the small end thereof and the nipple 58 is also fixed to the end wall 63 so that the moisture will be withdrawn through the inner hood 6|.

The inner hood 6| has secured to the large end thereof a screen or perviouswall 64 so that hair or the like will not be drawn into the interior .of the hood 6|. The outer shell 56 has fixed thereto an intake nipple 65 constituting the exhaust portion of the hood, with which the opposite end of the hose 54 is adapted to engage. The heated air which is discharged from the combined suction and pressure member 14 is adapted to be discharged in the chamber or air space 62 and about the outer surface of the in- Preferably, the outer end of the inner hood 6| is disposed inwardly from the rubber covering 66 so that the air discharged against the hair from the chamber 62 will pass beneath the perforate front wall 64 in order to ."more quickly dry the hair which is disposed in confronting position to the drying hood 55.

The crank shaft 2| has secured to one end thereof a grooved pulley 66 and an endless belt 6! is trained about the pulley 66. An electric motor 68 is disposed in laterally spaced relation with respect to the combined suction and pressure member 4 and is mounted on an adjustable platform 69 by fastening devices 10. The platform 69 is formed at the opposite edges thereof with depending flanges 1| which engage on opposite sides of the flanges 23 of the base [0.

The platform 69 is rockably supported from the base H! by means of pivot members 12 which engage through the flanges H and the flanges l3 adjacent the forward end portions of the flanges H. An upwardly extending threaded bolt 13 is fixed as at 1.4 to the base plate H and extends upwardly through an opening 15 which is formed in the platform 69. A nut 16 is threaded under the bolt 13 so as to provide for tightening of the belt 61. The motor 68 has a grooved pulley 11 mounted on the armature shaft '18 thereof and the belt 18 is also trained about the pulley 11.

A handle generally designated as 19 is .secured to the combined suction and exhaust mem- I ber 14 and includes a shank 80 provided with a outlet nipple 53.

boss 8| at the lower end thereof which is secured by a. fastening device'82 to the upper end portion of the base member I5. A laterally extending handle member 83 is formed integral with the upper end of the shank 86 and extends laterally or rearwardly from the cylinder l6. The shank also has formed integral therewith a forwardly extending lug 84 which is adapted to engage between a pair of the heat dissipating vanes I9 so that tightening of the single bolt 82 will firmly hold the handle structure 10 onto the combined suction and exhaust .member l4.

In the use and operation of this-device, the motor 68 is adapted to be connected to a suit able source of electric current supply so as to operate the combined suction and exhaust member l4. "The hair drying and dehydrating hood 55 is held in one hand of the operator and moved over the hair of the person. The moisture will be drawn into the inner hood member 6| onthe suction or downward stroke of the piston 26 and on the upward stroke of the piston 2|! which is the compression stroke, the valve member 26 will be disposed in a closed position, whereas the valve member 3'! will be open and the hair and moisture compressed in the cylinder |8 will be forced through the valve housing 38 into the collector 44.

The free moisture will be collected within the collector 44, whereas the air which is heated by the friction of the piston 20 in the cylinder l6 will be forced out of the collector 44 through the The heated air passing from the collector 44 will be forced through the hose 54 into the air chamber 62 and about the inner shell 6| so as to thereby heat the hair which is disposed within the area of the open or large end of the hood structure 55.

With a device of this kind, the hair may be dried more quickly than is .now the practice wherein a heated hood is disposed in encompassing position with respect to the head of a person, and the person is subjected toa considerable amount of heat until the hair becomes dry. Also with a device of this kind the hair may be dried more quickly without discomfort of the heated hood. 1

In order to provide a means whereby the air in the exhaust hose 54 may be positively heated, an electrical heating element 85 is interposed in the hose 54 and connected to a source of current supply. In this manner the air passing through the hose 54 may be heated to the desired degree independent of the heat generated-by the compressor 4. v
